PICKLING COMPOUND.

No Drawing.

To all whom it may concern:

Be it known that I, HENRY J. ORABBE, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Pickling Compound, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements, relating as indicated to pickling compounds, have more particular regard to a compound for use in pickling metals for the purpose of removing the scale and dirt from castings and hammered or forged articles. The usual compound used for this purpose is niter cake or salt cake, and it is one object of the present invention to provide a more efi'ective and equally inexpensive compound. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The following description sets forth in detail one approved combination of ingredients, such disclosed means constituting, however, but one of various ways in which the principle of the invention may be used.

My improved composition consists of bisulfate of soda and sodium chlorid, the preferred proportions being about 100 parts of the bi-sulfate of soda to about 41 parts of the chlorid. Preferably the bi-sulfate of Specification of Letters Patent.

Patented June llll, 11ers.

Application filed March 24, 1917. Serial No. 157,141.

soda should be very finely divided. In usecomplished in shorter time, while the cost of this compound is practically the same as that of other compounds used for the same purpose.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the materials employed, provided the ingredients stated by any of the following claims or the equivalent of such stated ingredients be employed.

1 therefore particularly point out and distinctly claim as my invention 1. A metal pickling compound comprising bi-sulfate of sodaand sodium chlorid in the approximate proportions of two parts of the former to one of the latter.

2. A metal pickling compound comprising one hundred (100) parts of bisulfate of soda and forty-one (41) parts of sodium chlorid.

gfagned by me, this 21st day of March, 1
